Monitor problem

[jbo]

I have a TFT monitor. In the past few days, i've started
to have a problem with it going blank. The power light
remains on, but it flickers slightly and then the screen
goes black. it happens at random times, and when the
computer is in use as well as idle. Is this a problem
with the screen itself, and do you advise taking it into
the place I bought it from? (I've only had it for 8
months).

Thanks for your help.
